Name the model which is described as "a number of protein icebergs floating in the sea of lipids" which explains structure and functions of a plasma membrane.

Answer

The model described as "a number of protein icebergs floating in the sea of lipids" that explains the structure and function of the plasma membrane is known as the **Fluid Mosaic Model**.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific model that describes the structure and function of the plasma membrane using a metaphor involving "protein icebergs" and "sea of lipids".

2. **Identifying Key Terms**: The terms "protein icebergs" and "sea of lipids" are crucial. They suggest that the model involves proteins embedded in a lipid bilayer.

3. **Recalling Biological Models**: In biology, there are several models that describe cell membranes. The most widely accepted one that fits this description is the Fluid Mosaic Model.

4. **Defining the Fluid Mosaic Model**: The Fluid Mosaic Model proposes that the plasma membrane is not a rigid structure but rather a fluid combination of lipids and proteins. The proteins can move laterally within the lipid bilayer, much like icebergs floating in the ocean.

5. **Conclusion**: Therefore, the model that fits the description provided in the question is the **Fluid Mosaic Model**.
